Collaborative German project to deliver power UV LEDs by 2020

December 06, 2017 // By Julien Happich
Last February was launched “UV Power”, a collaborative project funded by the German Federal Ministry of Education and Research (BMBF), bringing together five German research institutes and companies to deliver high-power UV LEDs.

As well as replacing conventional UV light sources, which often contain toxic mercury, in areas such as production, disinfection, the environment, life sciences and medicine, the UV LEDs are also likely to open up new areas of application.

As part of “Advanced UV for Life”, a consortium of research institutes and companies funded under the federal “Zwanzig20” program, "UV Power" project coordinator Osram Opto Semiconductors is working with four partners, the Ferdinand-Braun-Institut, Leibniz-Institut für Höchstfrequenztechnik (FBH), the Technical University of Berlin, LayTec AG and UVphototonics NT GmbH.

Prototype LEDs and the technology for producing high-power LEDs for the UVB and UVC spectrums are being built using the aluminium gallium nitride (AlGaN) material system and results will be presented by 2020 when the project comes to fruition.

“The various tasks have been distributed among the partners on the basis of their strengths – everything from the production of structured sapphire substrates, epitaxy and chip processing to packaging and analytics”, said Dr. Hans-Jürgen Lugauer, Head of UV Development at Osram Opto Semiconductors. To speed up development and make efficient use of resources, the partners are splitting their work into different wavelength ranges.
